The observations were made by the 1-m telescope of Yunnan Observatory over 2 nights. Their precise astrometric positions are derived from 989 CCD observations. The theoretical positions of asteroids are retrieved from the Jet Propulsion Laboratory (JPL) Horizons System and Institut de M\\'{e}canique C\\'{e}leste et de Calcul des \\'{E}ph\\'{e}m\\'{e}rides (IMCCE). The positions of three asteroids are measured with respect to the stars in Gaia DR2 star catalogue.
